I understand that it was a SMG and originally designed to have a short barrel.
But when adapted to be civilian legal here in the US it has a barrel that sticks out well past the front of the gun where the original barrel stops
My curiosity stemmed from the fact that if it was a bull pup design why would they add unnecessary barrel length onto the barrel of the civilian legal model. I imagined that it would have around 16" of barrel sunk into that little gun already as it was originally designed since it was a bullpup.
But that's where I messed up as its only a 10" barrel to begin with. And that extra barrel length is actually to make it 16". I'm not completely familiar with the gun besides fondling one long ago so I was not sure how far the action and breach was set back into the gun,apparently not as much as a thought.
